\( \cos ^ { 2 } 40 ^ { \circ } + \cos 50 ^ { \circ } + \tan 25 ^ { \circ } \times \operatorname { san } 65 ^ { \circ } \)

\( \sin ^ { T } x + \frac { \sin ^ { T } x } { 1 - \sin ^ { T } x } = \tan ^ { T } x \)

यदि \( \sin \mathrm{A}=\frac{3}{4} \), तो \( \tan \mathrm{A} \) का मान ज्ञात करो। If \( \sin \mathrm{A}=\frac{3}{4} \), then find the value of \( \tan \mathrm{A} \).

In terms of the sides of a right triangle, how would you express \( \tan(\theta) \)?

(22) If ABC is a triangle in which : \( 5 \sin \mathrm{~A} \sin \mathrm{~B}=6 \sin \mathrm{~B} \sin \mathrm{C}=9 \sin \mathrm{C} \sin \mathrm{A} \), then \( \mathrm{m}(\angle \mathrm{C})= \) \( \begin{array}{llll}\text { (a) } 28 & \text { (b) } 32 & \text { (c) } 36 & \text { (d) } 42\end{array} \) (23) If ABC is a triangle in which \( \cdot 6 a=4 h=3 c \), then the measure of the smallest
